Hi Sue, I think it would look amazing if you used some tiles with a bit of texture. The wood look tiles that are popular at the moment would be an example. If you chose a colour that toned in with your floor you would get a really nice cohesive look but with a bit of interest. I've attached a photo of a recent design of mine as an example. Just a suggestion!

We went with Monument and I am delighted. I was worried about it making the house hotter, but not at all as we added some extra insulation while the roof was lifted. We look over our roof to Mt Dandenong and it really feels like we are floating above the rooftops now (previously had a lighter color). I have also noticed there is far less glare being darker. Pic below is not my best shots ... but you get the idea. Forgot to add we also have a flat cliplock roof and used a combination of Monument and Dune on the house.

If you have a sample of it then Dulux can match it with a "Snapshot" digital colour analyser at one of the Dulux Trade centres. It matches any paint sample to the three closest standard paints. If you don't have a sample of it, and have only seen images of it on the internet then you are better off selecting one of the Dulux greys as it is too difficult to match from a digital image as there are too many variables with lighting, cameras and screens.

Is it possible that there are floorboards under the carpet that can be polished? This would be ideal. Otherwise, as much as I love my bedroom floorboards, I think you should stick with carpet. You’ll never match the hallway exactly so it will always look a bit odd.
